ALBERT ISKE, OF LANCASTER, PENNSYLVANIA, ASSIGNOR TO ISRAEL L. LANDIS, OF SAME PLACE.

COMBINED RAKE AND TEDDER.

SPECIFICATION forming part of Letters Patent No. 417,040, dated December 10, 1889.

Application filed September 16, 1889- Serial No. 324,115. (No model.)

To all 2072 0717, it may concern.-

Be it known that I, ALBERT ISKE, a citizen of the United States, residing at Lancaster, in the county of Lancaster and State of Pennsylvania, have invented certain new and useful Improvements in Combined Hay Rakes and Tedders, of which the following is a specification, reference being had therein to the accompanying drawings, in which Figure 1 represents a bottom View of my machine complete; Fig. 2, a vertical sectional View of the machine 011 the line x 00 of Fig.1; Fig. 3, a similar view on the line :r 00' of Fig. 1; Fig. 4, a detail sectional view of one of the ratchet devices upon the ends of the tappetshaft; Fig. 5, an elevation of the same; Fig. 6, a detail sectional View of one of the wheelhubs, showing manner of securing spur-Wheel thereto; Fig. 7, a detail View of one of the separable sectional tappets; Fig. 8, a front elevation of a portion of the machine, showing more clearly the automatic dumping devices; Fig. 9, a detail sectional view of the clutch device on the tappet-shaft; Fig. 10, a detail view of a portion of the endwise-movable hook-bearing rod and rear end of dumpinglever.

The invention has for its special obj ect the improvement and the simplification of that class of combined hay rakes and tedders covered by Letters Patent No. 398,165, granted February 19,1889, to I. L. Landis (the assignee in this case) and myself, wherein the en dwisemovable tappet-shaft and teeth-locking bar are so arranged that by the manipulation of a single lever the driver may simultaneously shift them in opposite directions, and thereby convert the machine from a hay-rake into a tedder, and vice versa, without dismounting, as will be more fully hereinafter set forth.

The invention also has for objects the provision of extremely simple means for automatically dumping the machine, utilizing for this purpose the rotation of the tappet-shaft, as will presently appear.

Another object I have in view is to provide means for insuring the operation of the tedding devices whether the machine be turning to the right or left-a great desideratum with this class of machines.

The invention has other minor objects in View, which will appear in the course of this the hollow tappet-shaft g, having loosel ournaled upon its ends the pinions h, which constantly engage the spur-whcels d, and are by the latter given rotation whenever the machine is drawn along. Secured upon the tappet'shaft adjacent to the inner faces of the pinions h are two ratchet-wheels Pivoted upon the inner facesof the pinions h, and engaging with the teeth of the ratchet-wheels, are pawlsj, which are actuated by springs k, secured to the pinions. By means of this ratchet-and-pawl arrangement the tappetshaft will be given rotation while the machine is moving forward, but will remain still while backing.

It will be observed that the teeth of the spur-wheels on the hubs are considerably say twice-wider than the teeth of the pinions, the objectin this being to permit the endwise movement of the tappet-shaft without disengaging the wheels. This arrangement avoids a drawback experienced in former machines occasioned by entirely disengaging the pinion from the spur-wheel, inasmuch as it was often diflicult to re-engage the wheels when it was again desired to convert the machine into a tedder, the teeth of the two wheels not always registering. It will also be observed that in this machine I employ two ratchet devices, one on each end of the tappet-shaft, whereas in all former machines only one ratchet device was employed. The use of one was found to be impractical to a certain extent, inasmuch as the tappet-shaft would remain practically still while the machine was being turned in one direction, thereby leaving a portion of the hay untedded. By placing two pinions and ratchets upon the tappet-shaft this difficulty is entirely overcome, as the tedding devices will continue to operate so long as either one of the transport ing-wheels revolves.

Along the tappet-shaft at suitable intervals are clamped the tappets Z, which are each constructed of two plates removably clamped over the said tappet-shaft by means of bolts. Thus making the tappets separable and removable enables me to readily renew any one of them, whenever worn or broken, without displacing or removing any of the remaining tappets'or the shaft. Below and a little to the rear of the axle is journaled the rakeshaft m, suitable brackets 02 being attached to the axle for its support. Upon the rakeshaft are pivoted the oscillating rake-sections 0, which are provided with the usual rearwardly-projecting rake-teeth and the forwardly-projecting arms 19, the latter being provided with rollers to receive the impact of the tappets. These rake-sections have a limited pivotal movement upon the rake-shaft by the means covered by the patent hereinbefore referred to. The brackets n are extended out rearwardly and then curved upwardly and forwardly and bolted to the top of the axle, as shown. These brackets are thus utilized as supports for the clearer-bar g, which is bolted to them.

Supported in arms 1', secured upon the ends of the rake-shaft, is an endwise-movable rod 8, which reci'procates directly beneath the rake-teeth and is provided with hooks to engage therewith. This rod is operated or reciprocated by means of a lever 25, pivoted in c a bracket to upon the bottom of the axle, and

provided at its rear end with a slot, through which passes a curved arm '11 upon the said rod, the forward end of this lever being provided with a pin, which is constantly in engagement with a grooved collar w on the tappet-shaft. This levert is shifted by means of a vertical pivoted lever a, which engages its forward end, and is provided with a pivoted locking-hook y. By thus connecting the tappet-shaft and locking-rod by a pivoted lever it will be observed that the machine may be converted from a rake to a tedder, and vice versa, by a single movement of a lever, the shaft and locking-rod being moved in opposite directions synchronously. This part of the machine is fully described and covered in the former patent hereinbefore mentioned, and a further description herein is deemed surplusage.

Bolted or clamped removably to the rakeshaft about midway its length is a horizontal dumping-arm a, which is provided at its rear end and upper side with a slot for the passage of the teeth-locking bar 3. The bars is provided with a slot 1), through which passes a pin 0' upon the arm a. This device pernits the locking-rod to be moved endwise independently of the arm a. The arm a in front of the axle is provided with a vertical extension d, which is connected by a link 6' to an operating lever f, which is pivoted upon the frame within easy reach of the drivers seat. By moving the-lever f in a backward direction the teeth may be elevated and the accumulated hay released.

For the purpose of automatically dumping the machine I have provided the following simple mechanism: Upon the tappet-shaft are located two clutch-sleeves g h, the former being secured rigidly to the shaft, While the latter is allowed a limited sliding movement, a collar being provided for limiting its movement. The adjacent faces of these sleeves are provided with ordinary clutch-teeth, and are normally held apart by means of an interposed spring Z. The sliding sleeve is op erated by means of a rock-shaftm, journaled in suitable bearings in the frame and provided with a depending arm n, which is constantly in engagement with a groove in the clutch h. The rock-shaft may be rocked by any suitable means; but I prefer to operate it by means of a foot-lever p, which extends up to within convenient reach of the driver. Formed integral with the sliding clutchsleeve is a radial arm or tappet q, which normally rests against a short pin 0" in the rockshaft m. hen the rock-shaft is partially .rotated by means of the foot-lever p, the

sliding clutch will be niovedinto engagement with the stationary clutch and the arm q disengaged from its pin 7'. Then, if the driver holds the two clutch-sleeves into engagement, the rotation of the tappet-shaft will carry the arm q around in the direction of the arrow shownin Fig. 2. As the arm q revolves, it will come in contact with the flanged roller 3' on the forward end of the dumping-arm a and force down the said forward end of the arm and elevate its rear end, thereby raising the rake-teeth a suliicient distance to release the gathered hay. As soon as the arm q passes the roller 3 the arm and rake-teeth will resume their normal positions, and the driver may then remove his foot from the foot-lever and permit the interposed spring to separate the clutches. Then the clutches become disengaged after (lumping, the friction between the sliding sleeve and its shaft will be sufficient to carry the arm q around until it rests upon the pin W-its normal position.

In ordervthat the rake-teeth may not drop too suddenly and be thereby injured, I may provide the end of the arm q with an upward extension 25, against which will impinge the flanged roller 8' as the rake-teeth resume their normal position.

It will be observed that if the extension 15 were not employed, as soon as the roller 8' reached the end of the arm q, it would leave it suddenly and permit the rake-teeth to fall violently to the ground; but by employing this extension and inclining it slightly rearward the momentum of the falling teeth is interrupted or retarded for a short distance by the roller .9 impinging against this extension, thereby breaking the force of the fall of the teeth. Flanging the roller .9 prevents the arm q slipping off the side of the roller during operation. It will also be observed that by using pinions and ratchets on both ends of the tappet-shaft all side draft while dumping with foot-lever is avoided.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is

1. The combination, in a combined hay rake and tedder, of a frame, transportingwheels provided on the inner ends of their hubs with spur-wheels cl, the rake-shaft, pivoted rake-sections provided with forwardlyextending arms 19, the tappet-shaft journaled in bearings in front of the rake-sections and provided with tappets, loose pinions j ournaled upon the ends of this shaft and held in constant engagement with the spur-wheels cl, these pinions being provided with teeth narrower than the teeth of the spur-wheel ratchet-and-pawl mechanism upon the tappetshaft adjacent to the said loose pinions, and means for shifting the tappet-shaft endwise, substantially as described.

2. The combination of the frame and transporting-wheels, the rake-shaft and rake-sections, the horizontal dumping-arm a, secured to the rake-shaft and provided with a roller, the tappet-shaft, the stationary and sliding clutch-sleeves thereon, the sliding clutchsleeve being provided with a radial arm, and

means for holding the two clutch-sleeves in engagement, as and for the purpose described.

3. The combination of a frame mounted upon transporting-wheels, the rake-shaft and rake-sections, a tappet-shaft, stationary and sliding clutches upon the tappet shaft, a spring interposed between the clutches, a radial arm carried by the sliding clutch, means for holding the sliding clutch into engagement with the stationary clutch, and a dump ing-arm a, secured to the rake-shaft and provided upon its forward end with a flanged roller, as and for the purpose described.
